Title: Improvements relating to shock absorbers for motor vehicles
IPC: B60G17/08
Filed: 1935-09-10
Abstract: 462,541. Shock - absorber systems. LUCAS, Ltd., J., and PITT, H. W. Sept. 10, 1935, Nos. 25135 and 30891. [Class 108 (iii)] In order to maintain the charge_of liquid in all the hydraulic shockabsorbers of a vehicle, a pump is combined with one of the shock-absorbers or is actuated by relative movements of the vehicle frame and a road wheel axle, and replenishes all the shock-absorbers with liquid drawn from a common container. Fig. 1 shows part of a system including a pair of oscillating-vane shock-absorbers g, a liquid container k, and an oscillating-vane pump combined with the left-hand shockabsorber. The pump supply pipe j is connected to the container, and the delivery pipe l to a fitting m from which radiate pipes n leading to the replenishing chambers of the several shockabsorbers, and a pipe o leading back to the container through a spring-loaded, non-return valve p. Oil issuing from each pipe n passes through a hole s to a filter plug t, Fig. 3, and restricted passage u to a pipe v, Fig. 2, leading to the lower part of the replenishing chamber. As the amount of oil in the replenishing chamber increases, the air in the upper part of the chamber is compressed and when the pressure exceeds a predetermined amount and while the pump is at rest, excess oil is forced back into the supply system through a release valve z. Continued action of the pump causes return of the liquid to the container k through pipe o and valve p. The chambers on either side of the vane b of each shock-absorber are interconnected by a passage e controlled by a spring-pressed valve f which is automatically regulated by the pressure in the system, some of the liquid issuing from each pipe n passing through a hole w, Fig. 1, to one end of the chamber containing the valve f, thus moving the valve in the direction to restrict the passage e. Liquid leaking past the valve is returned to the chamber g through a passage 2. Fluid-pressure on the valve f may be regulated by a handcontrolled valve 3. Various movable parts of the vehicle such as spring shackles, brake mechanism bearings, &c. can be lubricated through a pipe 6 leading from the container k and controlled by a valve 7.

Abstract: 1,259,833. Friction pivots for windows. TONKS (BIRMINGHAM) Ltd. 8 April, 1969 [27 May, 1968], No. 25193/68. Heading E2F. A window friction hinge particularly for a window pivoted about a horizontal axis comprises a hollow part 10, securable to a window frame, having a socket 11 to receive a spigot portion 12 securable to a window panel. The spigot 12 is formed with an extension 14 at one end which extends along one face of the glass panel 13 and is secured by way of a screw 15 and gaskets 17 through a hole in the glass to a part 16 extending along the other face of the glass. To prevent relative rotation of the extension 14 and part 16 they are formed with square or non circular spigot and socket formations. The end of the spigot portion 12 remote from the extension 14 is in the form of a cylinder 18 through which extends an axial bore 19 containing a headless screw 20 held against axial movement by a pin 21 transverse to the axis of the screw. The end of the bore 19 is of enlarged square crosssection and carries a member 24 of corresponding square shape. Between the member 24 and the cylinder 18 are a number of washers of which alternate ones 27 are fibre material with a high coefficient of friction and the rest are steel. The engagement of these washers resists relative motion between the socket 11 and spigot 12. The angular travel of the window is further limited by a plunger 34 in the bore 33 of a boss 32 formed on the part 10. A spring 36 urges the plunger 34 into a tapered recess 38, thereby limiting the rotation of spigot and socket.

Title: Improvements in urea-formaldehyde moulding compositions
IPC: C08K3/22
Filed: 1960-07-21
Abstract: Thermosettable moulding compositions comprise: (1) at least 75% of a mixture containing from 60 to 85% of a urea-formaldehyde resin and from 15 to 40% of total filler consisting essentially of a -cellulose; (2) up to 15% based on the total composition of a compatible, solid and stable chlorine-containing hydrocarbon derivative having a chlorine content of from 45 to 70%; and (3) from 0,5 to 10% based on the total composition of antimony trioxide.  The percentages are on a weight basis.  The chlorine containing hydrocarbon derivative is preferably a solid polymer or copolymer of a chloro-ethylene and may contain a low proportion of a comonomer such as vinyl acetate.  The minimum proportion of the chlorine compound is calculated by the equation <FORM:0912904/IV(a)/1> where P=weight per cent of chlorine compound and A=weight per cent of antimony trioxide in the solid composition.  Chlorine compounds exemplified are polyvinyl chloride, polyvinylidene chloride, a vinyl chloride-vinyl acetate copolymer derived from more than 80% vinyl chloride, a vinyl chloride-vinylidene chloride copolymer and octachloronaphthalene.  The chlorine compound may be stabilized by the addition of heat-stabilizers such as calcium carbonate, calcium stearate, tin stearate, zinc stearate, zinc resinate and inorganic salts of copper, zinc and manganese. Accelerators such as oxalic, benzoic, phthalic and hydrobromocinnamic acids, trimethyl phosphate, benzoyl peroxide and ethylene bis-benzene sulphonate; stabilizers such as hexamethylene tetramine and ammonium carbonate; plasticizers such as glycerine and its mono-ethers butyl urea and toluene sulphonamide; lubricants or mould release agents such as stearic and oleic acids and their zinc salts; and pigments such as titanium dioxide and Hansa yellow may also be added to the compositions. Examples are given in which the properties of various compositions according to the invention are compared with comparable compositions lacking either the chlorine compound or the antimony trioxide or both.  The preparation of the urea-formaldehyde resin used is by reacting 2 p.b.w. of urea with 3 p.b.w. of formalin (50%) for 3-5 hours, at a pH of 7-9 and at 25 DEG C.

As the needle cylinder 3 rotates, pattern jacks 1, as they approach a feed, are rocked outwardly about their upper ends, by the surface 14 of a cam 16, selected jacks are thereafter returned to inoperative positions by cams 36 on pin drum-controlled levers 37 pivoted one above another on a port 38; and longitudinal movement of the returned jacks is prevented by interaction between cam faces 8 on the jacks and a conical taper 9 formed on the needle cylinder below the level of the jack tricks, whilst radially outward movement is prevented by the interior surface of the jack lifting cam 17 behind which lifting butts 12 of the jacks have passed. Butts 12 of those jacks not returned by levers 37 ride up cam 17 to such a height that, through intermediate jacks 28, the upper butts 31 of needle sliders 29 are brought safely above the point 35 of needle raising cam 34. During passage of the butts 12 over section 21 of cam 17, their lower and upper cams 5, 6, bear against the bottoms 7 of the tricks 2 and the inner circumferential faces of cam rings 18 and 27 respectively. Butts 12 of any jacks which have been incompletely returned by cams 36 will start to rise up cam 17 butt, between points 22 and 23 thereon, will be free to slide off the cam and return to inoperative position before they engage their jacks 28. Raised jacks are lowered again by cam 26 acting on their upper butts 13. On the return strokes of reciprocatory knitting, the jack ends 55 are moved outwardly by winding 15 of the cams 16, but are thereafter returned by surfaces 25 on the cams 17.

Abstract: 1350467 Film transport mechanism EASTMAN KODAK CO 19 April 1971 [6 April 1970 (2)] 25921/71 Headings G2A and G2X Film is transported from the supply chamber 4 of a cartridge 1 to the take-up chamber 2 by means of a gear 13 on the chamber 2 which engages with a gear 12 on the camera 3, the gear 12 being turned by a knob 11. Gear 13 has a cover 22 so that the gear is manually inaccessible. As shown more clearly in Fig. 3, the plane A-A containing the axes of rotation of gears 12 and 13 is offset by an angle ° from the plane N-N which is normal to the film plane. This angle equals the pressure angle between the gears, and in the present example is 20 degrees. Thus the directional force resulting from the driving engagement of the gears is in the direction F. Since there is no force normal to the film plane, there is no need to provide means to prevent the cartridge being dislodged from the profiled parts 40 of the camera against which it is seated. The cartridge is contoured so as to have a seating pad 39 which contacts a part 40 of the camera along the line F, so that no unseating moment is caused by the force along the line F.

Abstract: 506,134. Plaster compositions. GRUNWALD, D. H. Sept. 6, 1938, No. 26015. [Class 22] [Also in Group III] A self-setting composition for heat and sound insulating purposes, consists of a slurry of calcium carbonate and magnesium carbonate prepared by carbonating a suspension of calcined dolomite in water and removing excess water as by decantation. The magnesium carbonate is obtained in the form of fine crystals hy carbonating at about 20-40‹ C., whilst agitating, excess carbon dioxide being avoided so that no magnesium bicarbonate is obtained, e.g. by using an open vessel and waste gases having a low carbon dioxide content. The setting is accelerated by heating the moulds preferably to 60-90‹ C., for example by placing the moulds in a chamber containing steam. After setting the products are removed from the moulds and dried at 70-200‹ C. Fillers such as asbestos, diatomaceous earth may be incorporated in the slurry. The product is normally porous but a more dense product may be obtained by applying pressure during the wetting.
